* Bratislava, August 9, 1890 – † Budapest, November 12, 1974 / chemist, university professor, corresponding member of the Hungarian Academy of Sciences (1945) ; ; He graduated from the Bratislava High School in 1908. He obtained a chemical engineering diploma from the József Nádor University of Technology in Budapest (1912). He began his work at the Plant Experiment Station in Magyaróvár, but after a few months he returned to the University of Technology in Budapest, where he was an assistant professor at the Department of General Chemistry under Lajos Ilosvay (1851–1936), and from 1915 he was an assistant professor. In 1916 he obtained a technical doctorate. In 1919–1921 he worked at the Department of Chemical Technology, and from 1921 to 1930 at the Department of Electrochemistry. In 1928 he was awarded the title of extraordinary professor. In 1930 he returned to the Department of General Chemistry. In 1936 he was appointed as a public extraordinary professor, and in 1940 as a university public full professor. After 1945 he was twice dean of the faculty of mechanical and chemical engineering of the university (1945–1946, 1947–1948), he was involved in the resumption of teaching at the technical university, which was severely damaged during the siege, and the damage to the building and equipment was repaired. He was retired in 1949. He carried out scientific work primarily in the field of analytical chemistry. In gas analysis he constructed novel gas pipettes, investigated the internal friction of gases and developed some new determination methods. In microanalysis he created new drop reaction detections. He also developed methods for the detection of hydrogen peroxide (H2O2) and the determination of cerium (Ce), gold (Au) and zinc (Zn). Between 1921 and 1943 he was the editor of the Hungarian Chemical Journal. During his basic research he also dealt with corrosion issues. In 1949 he was stripped of his academic membership, which was only restored in 1989. Only the first volume of his major work, Methods of Inorganic Chemistry, was completed in 1944. ; ; His main works: ; Complex Compounds, 1948, ; Methods of Metal Analysis (with László Mázor), 1949.
